Symposium on New Developments in Defect Mechanics - a unique intellectual event

Submitted by Cai Shengqiang on Tue, 03/04/2014 - 00:45

Faculty from Caltech, UC Berkeley , University of Michigan, Georgia Tech, Brown University, University of Calgary, University of Pennsylvania, UCLA, Johns Hopkins University, Imperial College, London, and UCSD and researchers from the Lawrence Livermore National Laboratories congregated to UCSD on January 18-19, 2014 to attend the third in a series of symposia on Multiscale Dislocation Dynamics and to honor Professor Michael Ortiz on his 60th birthday. Faculty also brought their graduate students and postdocs to engage in such a powerful intellectual activity.

Dynamic (explicit) to Static (standard) analysis

Submitted by apin87@hotmail.com on Sun, 03/02/2014 - 08:15

Greetings ,

i had successfully running my model in the step with dynamic (explicit).

BUT once i change my model with step in static (standard) then the job stop running in the half way with the error of

"too many increment in this step etc".. i had try decrease my small increment size to 0.001 but it still failed.. your help highly appreciated.

how can i solve this problems??

between, will it the result between Dynamic (explicit) to Static (standard) analysis difference??

Publication citation metrics and h-index for Australian Universities

opinion

h-index

For similar reasons outlined by Zhigang’s post node/2345 I
have found it necessary to find comparisons in publication citation
metrics/indices whilst in Academic employment. Much has been discussed about
the appropriate use of these metrics and the arguments on the benefits and
drawbacks are both compelling. Whatever your opinion, it seems that for the
foreseeable future these publication citation metrics are here to stay.

dispersive and nondispersive results!

Submitted by amceuma on Fri, 02/28/2014 - 14:22

Hi dear friends

I am working about wave propagation modeling in solids. in FEM for 1D beam model when governed differential equation of motion is solving by central difference method the output results of displacement are nondispersive but by using MATLAB "lsim" command for simulation of LTI system for arbitrary inputs, the outputs are dispersive which we expect this phenomenon will be happen in beam like models!

in bar models both methods leads to nondispersive results which is resonable.

could you help me?

crack propagation

dynamic fragmentation

statistics of fragment distributions

Hopkins Extreme Materials Institute (HEMI; hemi.jhu.edu) of The Johns Hopkins University is seeking a Postdoctoral Fellow to work on modeling fragmentation in brittle materials under extreme loading conditions. The potential candidate should have a Ph.D., with some background in fracture mechanics and experience working with the finite element or some other numerical method.
